Hello, I am using a web request control to mimic the 'related items' section as this is no longer possible after our 2013 -> 2019 migration.

The query is working fine, I am receiving the correct results, only after adding the XPath expression the results display double.

The setting to the web request:

When running the request it shows the proper XML outcome

When adding the XPath expression it shows the correct values, I guess.
(Sum is a calculated column)

Only on the form itself everything shows up double:

When changing "XPath for display" from "//z:row/@ows_Sum" to "//z:row/@ows_Title" I get ever stranger results on the form:

Should I change my XPath expression or is something else incorrect? I need it to be like image 4 and without the duplicate data.

Thank you.
